I VAPOR ATTACHMENT FOR EXPLOSIVE-ENGIN'ES.

tarmac.

To all whom it may coneem:

Be it known that I, GEORGE M. WA'i'rnns, a citizen of the United States,residing at Minneapolis, in thecounty of Hennepin and State ofMinnesota, have invented certain new and useful Improvements in VaporAttachments for Explosive-Engines; and I do hereby declare the followingto be a full, clear, and exact description of the invention, such aswill enable others skilledin the art to which it appertains to make anduse the same.

My invention has for its object to provide an improved device forsupplying water vapor with the explosive mixture to internal combustionengines; and to such ends, generally stated, the invention consists ofthe novel devices and combinations of devices hereinafter described anddefined in the claim. v I

Theinvention is illustrated in the accompanying drawings, wherein likecharacters lndicate like parts throughout the several views. Referringto the drawings:

Figure l is a side elevation showing the improved.vaporizer applied toanexplosii e engine; I

Fig.- 2 is a vertical section of the water trap of the vaporizer;

Fig. 3 is a detail in section on the line 3-3 of Fig. 2; and I Fig. 4 isa side elevation of the vapor-supplying valve.

In Fig. 1, the engine .is indicated, as an entirety, by the numeral 5,its intake manifold by the numeral 6 and the carbureter by the numeral7. The numeral 8 indicates a radiator of the usual arrangement having anoverflow pipe 9 of the customary arrangement. The instrument board oftheauton'iobile is indicated byfthe numeral 10. In the application of myinvention, I tap the overflow pipe 9 by a vaportube 11, and

this vapor tube is extended down-into thea irtight shell 12 of a watertrap or separator for separating the vaporfrom condensed water. .Thisshell 12, which is preferably 'in the form of a cylindrical drum "havingclosed heads, is preferably provided with two horizontal partitions13'f0rmed of very fine mesh, wire screen, preferably about 80 inesh. Thelower end of the vapor tube 11 terminates above the bottom of the tankbut below the lower screen 1 3. Between the two screens 13, the vaporpipe 11 is cut away, at least in part, and the opening iscovered bytype, which latter opens Specification of Letters Patent.- P t t t, .3,1913, Application filed September 30, 1916. Serial No. 123,023.. I i

a fine mesh tubular screen 14. The top of the drum 12 is connected by avapor tube 15 to a vapor supply valve of the petcock directly. into theThis valve coma tapered rotary fuel intake manifold 6. prises. a casing16 and valve 17, the latter having a depending arm.

18 connected to the front end of an operat ing' rod 19,.the said rodbeing preferably extended through and terminating in a knob by means ofwhich said valve may be freely moved to and from 'closed position.

In the bottom of the drum 12 is a drain port 21 that is normallyclosedby a lightly within the tank whenever the altitude of the waternearly reaches the lower end ofthe vapor tube 11, and in this way,automatically maintains an amount of water in the drum substantially asshown in Fig. 2.

My improved device supplies both air and water vapor but no solid waterto the manifold ofthe engine for admixture with the hydrocarbon 'vap'or.In the first place, only vapor will be drawn from the top oftheradiator; and in the second place, any water which condenses in the pipe11 and drum 12 will be precipitated to the bottom' of the drum. Some ofthe vapor -will escape through the tubular screen 14, and from thencewill pass upward through the upper screen 13 and to the engine throughthevapor tube 15, butsome will pass out of the lower end of the saidtube 11 and hence, if it is to reach the engine, must pass upwardthrough both of the screens 13. T ese two screens positively insurecondense water from reaching the tube 15.

In practice, the device has been foundeflicient for the purposes had inview. The water vapor afi'ords' suflicient dampness to remove carbon andkeepthe spark plugs and firingchambers free of carbon. It also rendersthe explosive mixture more efiicient and thus effects a saving in theuse of gasolene or automobile fuel.

What I claim is:

A water vapor supply device for explosive engines including a closeddrum having therein fine screen partitions, one above the other dividingthe drum into upper, intermediate and lower chambers, a vapor tubedelivering into said drum at a point be spring pressed drain valve 22mounted in a housing 23 secured tothe bottom of said drum. Thetension onthis valve 22 is such tween said screens andnvapor tube leading Intestimony whereof I afilx my signature from said cil irum at 2:1 pointabogre 1:118 upper in presence of two Witnesses.
